Formerly eggbound hen has stopped laying eggs altogether

Last week, one of my hens was eggbound for 3-4 days. She finally laid her egg, which looked like someone had eaten it, and then thrown it back up. (yuck!)

Since then, she hasn't laid anymore eggs. This isn't a problem for me as I'll just keep her as a pet. But I don't know what to be expecting here, if she'll start laying sporadically, or just not at all.

She was a 20 week old hen in April, so that makes her about 7-8 months old now?

If what you said were true, shouldn't she be suffering again? It would have been 5 days since she laid that last egg. And she's acting right as rain today. She's never been a consistent producer, but I think this is the longest I've noticed her going without laying now.
